Description of problem:
The /sbin/shutdown command allows shbutdowns after a delay.
During the delay period no logins are allowed.  However
shutdown fails to prevent other connections such as from
ftp.  (The command ftpshut does this but shutdown doesn't
invoke it.)  Shutdown should prevent ftp logins too, perhaps
all incomming TCP connections should be dis-allowed.

Another problem with delayed shutdown is that the warning message
issued fails to take into account the time interval used in the
"-t seconds" option.  For example:

    # shutdown -t 60 -r +10

will broadcast "System comming down for REBOOT in 10 minutes",
when of couse it should be "11 minutes".  Not using the "-t"
option is not a work-around since a second message at 1 minute
left is desirable.

How reproducible:
Always

Steps to Reproduce:
1./sbin/shutdown -t 60 -r +10 "Test reboot"
2.ftp localhost
3.

Expected Results:  Correct time remaining (perhpas rounded to the nearest minute),
and new FTP connections dis-allowed.
